  Is it possible to apply numeric formatting as you type.  I am looking to achieve something similar to the asp.net ajax control toolkit maskedinput.
  http://www.asp.net/AJAX/AjaxControlToolkit/Samples/MaskedEdit/MaskedEdit.aspx
  
  Or maybe I have to write my own formatter and bind it to the onkeypress.  Wanted to see if it can be done out of the box first.
  
  Thank you.

  Thanks for the reply. I had seen both those articles prior to posting here.  I do not see how I can provided the formatting as the user is typing the input.  The demos show formatting applied after losing focus from the control.  I need to be able to show the same as they are typing also.
  
  Thanks.

  Hello anand,
  
  You can use RadMaskedTextBox control. The RadMaskedTextBox is an enhanced data entry control that uses a mask to distinguish between proper and improper user input. To change the mask that is used to format the value when the masked text box does not have focus (for example, to change the literal strings in the mask), set the DisplayMask property. When a RadMaskedTextBox control is displayed at run time, it represents the mask as a series of prompt characters for the text the user should enter and literal characters for literal strings that are part of the mask. Each mask position is shown with a single prompt character. You can specify the prompt character that the masked text box uses by setting the PromptChar property - review this online demo

  @anand 
  Did you resolve you problem?
  @Telerik
  I get the same problem.
  Example: when user type 85000000 -> lost focus -> then display 85,000,000
  so how can display 85,000,000 without lost focus
  The general: typing -> display
                       1500      ->  1,500
                       30000    -> 30,000
  It looks like RadNumericTextBox with
  

  EnabledStyle-HorizontalAlign ="Right"

  NumberFormat DecimalDigits="0" GroupSeparator =","

  But RadNumericTextBox can not formated when typing, It only formatting when control lost focus.
  I have try with RadMaskedTextBox but can't find out the way.

  I was not able to accomplish with the Rad controls, so i had to go with a jquery alternative
